[Crash] Thumbnail Viewer Crashes Explorer

[Bhikkhu Pesala]

When I tried to view the thumbnails of PDF files in Windows Explorer, the first few files showed up OK, but then I got a Debug Assertion Error.

I thought this might be due to a very large (279 Mbytes) test PDF I had in the folder (the thumbnail for that displayed OK after a short delay), so I moved it to a temporary folder, but I still get the error every time.

Error message and a couple of crash logs are attached.

Thanks Bhikkhu, will check why this can happens and will fix.

Seems to be fixed OK now in the latest beta version.

Reason is because in the previous archive the debug version (compiled at the end of august) of shell extensions was included

Looks like this bug is baaack!
OK. I haven't tried the Shell Extensions until now but today I decided that it might actually be a nice feature.
So, I hit Help->Check For Updates and I was prompted to install the latest available version of the extensions (I already had the latest viewer build)
So, I opened a folder with some pdf's in it and I selected View->Thumbnails.
I was greeted by the same behavior as Bhikkhu described in his initial post.
Attached is the crash log and a screenshot.

Can you check on which file it is crashed ?

[benradu]

Seems to be the attached one.
It's the only one left in a folder.

Hi,
I already sent an email about this crash via the report a problem function of the viewer on January, 23rd. But since I didn't get a response until now, I think either my mail or your response was classified as spam by a filter. So - to be sure, that you're aware of the problem, I'll post it here:

When the shell extension tries to create a preview image for the
attached pdf, explorer.exe crashes.

My configuration:
Windows XP, SP3 32bit,
XCShInfo.dll version: 2.0.40.7 (from latest PDF-XChange Viewer package)

Steps to reproduce the problem:
- Place the pdf in any folder, such that the extension tries to create a thumbnail image
=> explorer.exe crashes

What I tried to solve the problem:
- Extract page with PDF-XChange Viewer to a new document, but problem persists
- Print document with PDF-XChange printer driver: problem is solved, the new document doesn't crash the shell extension anymore, but I'm sorry, I wasn't able to figure out, how to produce a pdf which remains searchable. Is this possible with PDF-XChange Viewer? If yes, what am I supposed to change in the (printer) settings? (Print as image was
already unchecked)

Thank you,
Mike
